what would you do with 10x20?
« on: August 22, 2010 »
Ok, lets say you have a 10x20 foot LED display board with the same resolution of pixels. It should be able to do full 32bit rgb, at a reasonable fps. It will be driven by a windows computer, so you don't have code constraints that way. I know this forum has had low res competitions, but I'm not sure any are quite that low. I know I've seen some things that would probably still be pretty neat looking at this low of a resolution, plasma for instance, but the more ideas the merrier. Also due to the nature of LEDs, it would be best to stay away from pure reds (0xff0000) for brightness, but otherwise no real constraints. If you want to suggest new ideas, or link me to old demos / effects that would take advantage of this medium that would be much appreciated, thanks!

[FYI, my school is considering building one which could be used to play tetris, but for legal reasons it would have to do other things most of the time. Naturally I thought of graphics demos, and subsequently thought of this forum. I will keep you guys informed if this becomes a reality]

You can do some excellent scroll-texts in that kind of res.

Is it an LED that has green/orange/yellow only, or is it a more modern one that has blue too?

What about a Pong like game? 1 LED = Ball  3-4 LEDs for paddles? ;)
Or maybe a rotating cube?

AS Jim already said... a scroller or a Sinusscroller....

10x20 appears very low but one could try to draw at a higher resolution (eg. 30x60) and downsample the result - the brain is often very imaginative with such color-sludge.

@vai!n: yea I've thought of pong or breakout would probably 'work' at this res. Maybe even a single pixel per ship version of space invaders.

@Jim: Scroll-texts would probably be pretty cool, and at a campus I'm sure we would have plenty of things to scroll. Its a full RGB LED package with all 3 colors, so any color should be possible.

@hellfire, thats a good idea, I'll have to fiddle with that. :)

So far I've hacked up a waterfall effect with scrolling blue pixels and white particles bouncing at the bottom, some gradient color rotations, and I reconfigured that game of life fade demo thing I submitted way back when for some compo on here. They all look pretty cool even at that res, I'm hoping I'll be able to see them irl. ;)

Keep the ideas coming. :)

Fire would be something that I think would look pretty good in that resolution in an 8 bit kind of way.

I only say that because I remember messing around on a spectrum a long time ago and I accidentally made a fire effect, it was very blocky and probably horrible but you could still tell it was supposed to be fire.

This sounds like a nice project ...

I made a little javascript library which uses table cells as pixels/leds. Here are some
examples - maybe it is useful for doing some prototyping...

Fire
Resolution: 10 x 14
URL: http://www.jsfbgl.weltenkonstrukteur.de/works/jsfbgl/Fire.html

Snake
Resolution: 20 x 20
URL: http://www.jsfbgl.weltenkonstrukteur.de/works/jsfbgl/Snake.html

Some more infos/demos here.

Anyway, good luck and keep us informed about the progress you make...

Perhaps I'm reading this wrong - are the LED's a foot across?

Well, each "pixel" is a foot across, and will be driven by a number of super bright LEDs.

Jim, that was probably the best idea this thread has to offer! close encounters of the third kind is WIN!


anyways, i'll see if i can come up with something cool.. the first thing that came to mind though, was some sort of spectrum analyzer :)

Man, how I wish this comp has java and flash installed.

Deleter:  How about a "space jockey" clone.  It's an old atari game.
